Answer :
At twelve weeks Tim will have $62
Mike will have $160
The balance will be the same at $114 at eight weeks
Mike will have $160
The balance will be the same at $114 at eight weeks
Answer:
After 8 weeks they will have same account balance and after 12 weeks Mike's account balance will be $160 and Tim's account balance will be $62.
Step-by-step explanation:
Let t be the no. of weeks .
Mike has $22 in his bank account
He deposit $11.50 each week
He deposits in t weeks = 11.50t
So, total amount in Mike's account after t weeks = 22+11.50t
Tim has $218 in his account
He is withdrawing $13 each week.
He is withdrawing in t weeks. = 13t
So, total amount in Tim's account after t weeks = 218-13t
Now to find When will the account have the same balance :
22+11.50t=218-13t
13t+11.50t=218-22
24.5t=196
[tex]t=\frac{196}{24.5}[/tex]
[tex]t=8[/tex]
So, after 8 weeks they will have same account balance .
Now Their account balances after 12 weeks:
Mike's account after 12 weeks = 22+11.50(12)=$160
Tim's account after 12 weeks = 218-13(12)=$62
Hence after 8 weeks they will have same account balance and after 12 weeks Mike's account balance will be $160 and Tim's account balance will be $62.
